Bronchial Inflammation and Hyperresponsiveness After Oil Supplementation
Exercise-induced Asthma
About this trial
This is an interventional diagnostic trial for Exercise-induced Asthma focused on measuring exercise-induced asthma, cold chamber, exercise challenge, cold air challenge, oil supplementation, middle-chain and Polyunsaturated Fatty Acids

Placebo Comparator
Oil supplementation verum
Oil supplementation placebo
30 patients aged 12-44 years with a diagnosis of exercise induced asthma undergo a methacholine challenge and a prick test. After randomization patients will receive in double blind approach ones daily 1190 mg of middle-chain and polyunsaturated fatty acids for four weeks. Before and after supplementation an exercise challenge in a cold chamber will be performed.
